ConnectionEndPoint class

Defines the visual marker at the start or end of a connection.

A ConnectionEndPoint specifies the shape, size, and colors of decorative markers (like arrows, circles, or diamonds) that appear at connection endpoints. These markers help visually indicate the direction and termination points of connections.

Common Use Cases

  • Arrow heads to show data flow direction
  • Circles or diamonds for aesthetic purposes
  • No marker when a clean line is desired

Usage Example

// Create a custom endpoint with colors
const myEndpoint = ConnectionEndPoint(
  shape: MarkerShapes.triangle,
  size: Size.square(8.0),
  color: Colors.blue,
  borderColor: Colors.blueAccent,
  borderWidth: 1.0,
);

// Use predefined endpoints
const arrowEnd = ConnectionEndPoint.triangle;
const circleEnd = ConnectionEndPoint.circle;
const noEnd = ConnectionEndPoint.none;
